HOSE-MENDER.

SPECIFICATION forming part of Letters Patent No. 567,962, dated September 22, 1896.

Application led June Z3, l896 ifull, clear, and exact description of the inven-` tion, such aswill enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this My invention relates to the class of devices adapted to be employed in repairing or mending ruptured garden-hose.

In certain types of hose-menders it has been usual hitherto to provide the interior of the hose at ,the adjacent severed ends with a short metal tube or sleeve, the latter being firmly held in place by one or more clamps encircling the exterior of the hose. IVhile such former devices may prove to be efficient and strong, it is obvious that in order to thus unite orjoin the severed ends of the hose a person must possess considerable skill, the

operation also requiring a comparatively long time.

The object I have in view is to produce a 'hose-mender in which the defects or disad- Fig. 2 is a sectional view, in partial'central section, showing the device combined with a hose `as in use; and Fig. 3,- is a transverse section taken on line :c of Fig. l. y 1

of brass or other suitable metal, say about six inches in length, its outer diameter being 'substantially the same as the normal internal diameter of the hose. Each end of the tube is enlarged, so as to form a raised flange b. The same is inclined 'rearwardly and terminates in a comparatively sharp edge or ridge b', the latter being at substantially right an-` gles to the barrel portion aof the tube, thus forming a shoulder b2. cylindrical portion a of the tubeis provided 'with two series of outwardly-projecting oppositely-faeing sharp spurs or teeth c. These spurs are made hooking or sloping and are arranged around the barrels surface at suitble intervals, the/inclination of the spurs being toward the rear or center with respect to the ends of the tube, or substantially the same as the inclination of the said flanges b, as clearly shown. The height of the spurs c above the barrel Ashould not exceed that of the endl-langes.

I prefer to make the spurs integral with the tube. They may be produced in anysuitable manner, as, for example, Iv may form them by the use of a suitable tool, the end of which is forced into the metal, say by the blows of a hammer, thereby throwing up the adjacent metal in the form of burs or spurs in a nianner analogous to the formation of teeth on a coarse iile or rasp. By the use of a suitable machine the spurs can be produced mechanically and rapidly. l

In using my improved hose-mending device a the adjacent ends h h of the severed hose are simply forcedendwise over the corresponding `ends of the tube, therebyV at the Sametime slightly expanding the hose until the hose ends abut, substantially as shown in Fig. 2. Owing to the beveled or sloping sides The said barrelv or of the ianges and spurs but comparatively` little resistance is offered to the insertion of the tube. The yielding material of `which the hose is composed then contractsaround the several spurs and anges, thereby causing them to' become embedded therein. Now when water under pressure is let into the hose its action will be to still further embed the spurs into the hose, while the Iianges b at the same `time so 'distend the hose thereat, as indicated at h', as to prevent Waterfrom pass ing beyond them tov the barrel part of the IOO joint.
